Today, buildings are responsible for approximately 40% of energy consumption in the EU, making them the single largest energy consumer in Europe. At present, about 35% of the EU’s buildings are over 50 years old and almost 75% of the building stock is energy inefficient. Renovation of existing buildings can, therefore, lead to significant energy savings, as it could reduce the EU’s total energy consumption by 5-6%.

Energy Efficiency Index (EEI) as an indicator used to track the performance of energy consumption in a building.

The accurate forecasting of energy consumption in a building is an important strategy in achieving the goal of reducing energy demand, as well as to improve energy efficiency. To implement this strategy, many methods and indicators have been proposed to monitor and measure energy performance in buildings. However, various factors that influence the energy consumption of a building system operation, such as the types of activities carried out in the building, weather conditions, building materials, HVAC system, and occupancy; contribute to the difficulty in accurately measuring a building’s energy system.

WINERGY manages to calculate the energy efficiency index of any type of house in a certain and accurate way through the instrument of its Analytic Tool. Hence, WINERGY determines the energy consumption problems for householders and help householders being aware of their unconsciousness about energy efficiency. The first step to using energy productively at home is to determine energy consumption problems correctly. Here, we do our best with you.

The Analytic Tool can calculate the energy efficiency score in 21 different countries including countries such as Germany, Sweden, Denmark, and Canada, etc.
